The application provides a copper plating solution and a stabilizer, which comprises copper sulfate pentahydrate, a complexing agent, formaldehyde, ethanolamine, 2,2-bipyridine, S-adenosyl-L-homocysteine, S-carboxymethyl-L-cysteine and thiomalic acid. The S-adenosyl-L-homocysteine and the S-carboxymethyl-L-cysteine can improve the tolerance of the plating solution to leached palladium. After a certain amount of thiomalic acid is added, the three components have a good synergistic effect. The plating solution maintains high activity and further improves the tolerance to leached palladium, which is beneficial to improve the service life of the plating solution and prolong the decomposition time of the plating solution. Even under high leached palladium concentration, the thick copper solution does not affect the plating activity and the uniform plating capacity of the chemical copper plating solution. Under normal production load, a deposition rate of 1.0 um / 20 min can be obtained. The solution has good stability. Under extreme conditions of high leached palladium, the decomposition time of the plating solution is prolonged by 2-6 hours.
